Statement: In absence of external force total momentum of system remains constant.

• • RECOIL OF GUN • •

Mass of shell = m1
Mass of gun = m2
Velocity of shell = v1
Recoil velocity of gun = v2

Initial momentum = Final momentum
0 = m1v1 + m2v2
v2 = -(m1v1) / m2

Recoil velocity of gun is (m1v1 / m2) in opposite direction of velocity of shell, hence -ve sign.

Answer:

Mass of shell = m1

Mass of gun = m2

Velocity of shell = v1

Recoil velocity of gun = v2

Initial momentum = Final momentum

0 = m1v1 + m2v2

v2 = -(m1v1) / m2

Recoil velocity of gun is (m1v1 / m2) in opposite direction of velocity of shell, hence -ve sign.
